Slide 12
Key Features • Factory filled and hermetically sealed l eak eak--free in any orientation – quick to install
• Self-contained - no separate power unit no pipes or fittings to install or to leak
• No solenoid or servo-valves simple and reliable
• Motor-Controlled Operation precise positioning and speed speed
• Load -lock on loss of power
check valves hold load indefinitely and safely
• Quiet
no gear train noise
Slide 13
Value Proposition: M-Mac vs HYDRAULIC
• • • • •
Fast & clean installation No leaks & no maintenance Same performance & life Same cost Other advantages: – – – – –
High efficiency / low power draw No solenoid valves No hoses, pipes or fittings fittings No oil contamination of oxidation Factory filled & sealed
Slide 14
Value Proposition: M-Mac vs PNEUMATIC
• Better reliability • Better performance (stiff action and higher force) • Less cost • Other advantages: – – – – –
Lower energy draw No piping No airlines to freeze Internal corrosion/jamming eliminated Less noise
Slide 15
Value Proposition: vs SCREW ACTUATORS
M-Mac
• Twice the force density • Five-to-ten times the life • Same cost • Other advantages: – – – –
Tougher (dirt, moisture, abuse, heat, shock) Higher efficiency / lower power draw Safer (load(load-lock by check valves) Quieter
